******"April" might be the most curious project Deep Purple ever did in studio, and it is certainly the most complicated one. It is a 12 minute long piece consisting of three distinct sections. The first two sections are instrumental, while the third one is a rock song like the others on the album. The first section is started off with a long organ introduction, followed by some acoustic guitar. Following this is an electric guitar solo, which up to this point in Ritchie Blackmore's career was the longest guitar solo he had played on record. After the guitar solo ends, there is a classical-sounding piece for 12-piece chamber orchestra, composed by Lord but with no Deep Purple members playing. This second section is also the longest one. After different aspects of woodwinds and strings, the third section - a more straight-ahead rock song - begins, introduced by a short drum fill. Then Rod Evans starts to sing Jon Lord's lyrics. The song ends with another guitar solo, which gradually fades out.
